Drivers traveling through Nassau have been warned: cameras have started snapping photos of school zone speeders.

White vans equipped with photo radar are now operating in front of select schools in Nassau County. Drivers who go more than 10 mph over the posted speed limit will receive tickets in the mail for $80. So far, the cameras are active in Hempstead, North Merrick, Bethpage, Levittown and Elmont.

When the program is fully deployed, Nassau drivers will see one mobile camera van or one permanent speed camera per school district. The cameras will issue violations during school hours, including summer school. Signs will be posted warning drivers that there may be speed camera enforcement in the area, according to officials.

Officials estimate that Nassau could generate as much as $25 million a year from cameras, but that number is expected to reduce over time as people realize the areas are enforced.

One of the heaviest periods for electricity use also will see among the lowest costs for customers as PSEG Long Island this summer cuts the power-supply charge portion of bills to a near-record low.

After months of increases in their electric bills through a cold winter, Long Island ratepayers who use around 775 kilowatt hours could see an average $13 reduction in their bills this month as lower demand for natural gas leads to a break in prices.

The power supply charge fell 20 percent for August to 6.78 cents a kilowatt hour — the lowest it has been in at least a year — from 8.5 cents last month. The charge reached record highs this winter, topping 12.3 cents in March, as cold weather led to soaring demand and prices for natural gas. Eight of the last 13 months have seen power-supply charge increases

A man who recently traveled to a West African country combating an Ebola virus outbreak has been quarantined at Mount Sinai Hospital in Manhattan.

Hospital officials emphasized in a news conference Monday evening that they were placing the man in isolation as a precaution. They stressed that it was more likely that the patient didn’t have the Ebola virus and that people who had come into casual contact with him — including those in the emergency department — were not at risk of being infected.

Sid Dinsay, a spokesman for the hospital, had said earlier that Monday morning “a male patient with high fever and gastrointestinal symptoms” came to the hospital’s emergency department.
